Manga artists tell stories with a single panel. Their secret is selective specificity: they do not draw every detail of a room — they draw the one detail that tells the story. A cracked tea cup.
A sword with a notch. A hand that is shaking. Bring this principle to your prose.
Instead of describing your character's entire appearance, give the reader one image that does all the work: 'He had the hands of someone who had never apologized for anything.' Visual storytelling in text means writing in images, not in summaries. 'She was sad' is a summary. 'She laughed at the wrong moment' is an image.
